SAN SHING SK-2240 MANUAL LATHES

Technical Description

The SAN SHING SK-2240 manual lathe is a heavy-duty precision machine featuring a 21.97-inch swing capacity and 40-inch distance between centers, suitable for large workpieces. It is powered by a robust 7.5 HP motor, delivering up to 1,200 RPM spindle speed. The lathe includes a 3.05-inch spindle bore allowing the machining of sizable shafts and parts through the spindle. The swing over the cross slide is 13 inches, providing enhanced versatility for various turning operations. The machine’s bed is constructed from high-strength cast iron (FC-25), engineered with a box-section design and ribbing to ensure superior rigidity and stability during heavy cutting tasks. The spindle is precision ground and supported by high-precision bearings at three points, ensuring smooth and accurate spindle rotation. The headstock comprises hardened, alloy steel gears and splines, with a dial rotary system designed for rapid and simple speed changes. The apron and carriage feature an adjustable overload safety device, and the slide surfaces benefit from manual and automatic dual lubrication systems to reduce wear and maintain accuracy. Additionally, the lathe includes features such as metric and inch thread cutting without gear changes, emergency braking for operator safety, and a tailstock with reduction gearing for versatile drilling operations. The gap bed design allows machining of large diameter workpieces or components with irregular shapes. This machine is suited for heavy-duty applications requiring precision, durability, and reliable performance in metal turning and cutting tasks.
